This reminds me of the Charlie card for using the subway in Boston:

It has fun history, apparently they were going to introduce a nickel tax to get off the subway, so the legend is that Charlie never got off, because he didn’t have a nickel.

Nearly happened to me on the Tokyo subway. Train from Narita to Tokyo, couldn't find a way to get out of the system in Shibuya.
